MK11 18” .308 Upper Receiver
The Centurion MK11 18” upper chambered in .308 is a factory built Centurion Upper receiver, compatible with MK11, LMT MARS-H and KAC SR25 Lower Receivers. This upper receiver features a 16 inch 416R precision stainless 1:10 Twist barrel chambered in .308 with a rifle length gas system for enhanced reliability and a smooth recoil impulse. The barrel features a Centurion signature notch, allowing for perfect alignment between the gas block and barrel. The gas blocks on these uppers are also pinned.
The upper has a Centurion 13.5” Quad Rail handguard mated up to a MK11 billet upper. The upper to handguard interface is further secured with an anti-rotation pin that further secures the handguard and upper receiver connection.
These uppers come with an A2 flash hider and charging handle. Each upper is test fired at Centurion during the manufacturing process.
Does not include BCG. We recommend the LMT .308 BCGs available HERE
